问题描述
我正在尝试安装OpenCV以与Visual Studio一起使用.我正在使用2012Pro版本，但我认为它应该与vs10相同. 我正在关注本教程: http://docs.opencv .org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to
Im trying to install OpenCV to work with Visual Studio. I'm using the 2012Pro version but I think it should be the same as vs10. I was following this tutorial: http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to
我有一个仅包含一个项目且仅包含一个文件的解决方案.为了进行测试，我使用了与教程中相同的代码.
I have A Solution with only one Project And with only one file. For testing purposes I used the same code as in the tutorial.

我已经下载了2.4.3版本，并将其解压缩到C:\ BUILD \ 所以现在我有了C:\ BUILD \ opencv等等
I've downloaded the 2.4.3 version and I extracted it to C:\BUILD\ So Now I have C:\BUILD\opencv and so forth
在visual studio的属性管理器中，转到Microsoft.Cpp.Win.32.user工作表，然后更改以下内容:(根据堆栈中所说的教程和此处的其他解决方案)
In the property manager in visual studio I go to the Microsoft.Cpp.Win.32.user sheet and I change the following: (according to said tutorial and other solutions here in stack overvlow)
在 C/C ++->常规中，我在其他包含目录
C:\BUILD\opencv\modules\core\include\opencv2\core
C:\BUILD\opencv\include\opencv
C:\BUILD\opencv\include\opencv2
C:\BUILD\opencv\build\include
C:\BUILD\opencv\build\include\opencv2
C:\BUILD\opencv\build\include\opencv
在 Linker-> General 中，我在其他图书馆目录
C:\BUILD\opencv\build\x86\vc10\lib
在 Linker-> Input->其他依赖项
opencv_core243.lib
opencv_imgproc243.lib

(是的，我知道调试用的d.但是都没有用)
(yes I know about the d for the debug. But neither is working)
我尝试构建解决方案，但出现以下错误:

推荐答案
您是否已将OpenCv路径添加到环境详细信息"?通常，这是大多数教程告诉您要做的第一步.
Have you added the OpenCv path to your Environment Details? it is usually the first step that most of the tutorials tell you to do.
However if this does not work here is the link that I always use to help me set it up. It is using version of VS 2012 and OpenCV 2.4.3, so it is very similar to your problem.
这篇关于在Visual Studio 2012中安装OpenCV的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
